Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| K. P. Schmidt 1931 | Mesoplastral bones widely separated, situated on the bridge. Posterior lobes of plastron with deep emargination whose outline is nearly circular. Inner angle of the mesoplastrals well outside the lateral contour of the plastral lobes, produced across the bridge. Nearest ally (suggested), the living P. sextuberculata of theupper Amazon region. | |
| E. S. Gaffney 1975 | Plastron relatively wider than in T. sulcatus; xiphiplastral notch deeper and more circular than in T. sulcatus; anterior plastral lobe relatively shorter and more rounded than in T. sulcatus; xiphiplastral points closer together compared with T. sulcatus. |
